Video Analyses of Dr. Marshall's Baseball Pitchers

&nbsp&nbsp&nbsp&nbsp To watch the video and high-speed film of the baseball pitchers that I have trained, in the column to the right, visitors need to click on the name of each baseball pitcher.

&nbsp&nbsp&nbsp&nbsp Unfortunately, to be able to put these videos on line, we had to severely compressed them, such that the clarity is not as good as on the DVDs I make.&nbsp Nevertheless, visitors will still see clearly enough to determine how well each baseball pitcher performs my baseball pitching motion.

&nbsp&nbsp&nbsp&nbsp To analyze baseball pitchers, we need to develop a system that checks for all flaws.

&nbsp&nbsp&nbsp&nbsp To succeed at the highest level of baseball, baseball pitchers need a wide variety of high-quality pitches.&nbsp Therefore, the purpose of the first video segment is to evaluate the quality of the movement of these pitches.

02.&nbsp In the second video segment, I slow the video down to one-quarter speed.

&nbsp&nbsp&nbsp&nbsp To eliminate injuries to the front of the pitching shoulder, when their glove foot lands, baseball pitchers need to have their pitching arm ready to move toward home plate.&nbsp Therefore, the purpose of the second video segment is to determine the position of the pitching arm when the glove foot lands.

03.&nbsp In the third video segment, I provide real-time front view video of my baseball pitchers throwing my six basic pitches for adult baseball pitchers.&nbsp Therefore, the purpose of the third video segment is to again evaluate the quality of the movement of these pitches, but from the batters perspective.

04.&nbsp In the fourth video segment, I again show the video down to one-quarter speed.

&nbsp&nbsp&nbsp&nbsp Home plate is seventeen inches wide.&nbsp The pitching rubber is twenty-four inches wide.&nbsp Therefore, three and one-half inches on either side of the pitching rubber is outside of home plate.

&nbsp&nbsp&nbsp&nbsp When baseball pitchers release their pitches outside of home plate, they have to throw the baseball inward toward home plate.&nbsp Therefore, the purpose of the fourth video segment is to determine the position of the pitching hand at release with reference to the pitching rubber.

&nbsp&nbsp&nbsp&nbsp a.&nbsp For my Maxline pitches, I want my baseball pitchers to release the baseball outside of the glove arm side of the pitching rubber.

&nbsp&nbsp&nbsp&nbsp b.&nbsp For my Torque pitches, I want my baseball pitchers to release the baseball outside of the pitching arm side of the pitching rubber.

05.&nbsp In the fifth video segment, I show high-speed film of my pitchers from the front view.

&nbsp&nbsp&nbsp&nbsp High-speed film from the front view shows from where my baseball pitchers start the acceleration phase of their pitching motion, how they accelerate their pitches through release and how they decelerate their pitching arm and body.

&nbsp&nbsp&nbsp&nbsp To focus on the critical moments of the baseball pitching motion, I freeze framed the film at four different moments.

&nbsp&nbsp&nbsp&nbsp a.&nbsp 'End of the Pendulum Swing.'

&nbsp&nbsp&nbsp&nbsp The 'End of the Pendulum Swing' is the moment immediately preceeding the acceleration phase of the baseball pitching motion.

&nbsp&nbsp&nbsp&nbsp Immediately after the end of their pendulum swing, baseball pitchers start accelerating their pitching upper arm toward home plate.

&nbsp&nbsp&nbsp&nbsp To engage their Latissimus Dorsi muscle, my baseball pitchers should raisetheir pitching upper arm to vertically beside their head and turn the back of their pitching upper arm to face toward home plate.

&nbsp&nbsp&nbsp&nbsp If my baseball pitchers have the back of their pitching upper arm toward home plate, then they are using their Latissimus Dorsi muscle to vertically drive their pitching arm forward.

&nbsp&nbsp&nbsp&nbsp If my baseball pitchers have the inside of the pitching upper arm toward home plate, then they are using their Pectoralis Major muscle to horizontally pull their pitching arm forward.

&nbsp&nbsp&nbsp&nbsp In the 'Maximum Pitching Forearm Acceleration Position,' my baseball pitchers have their pitching elbow slightly above the top of their head with their pitching forearm horizontally behind their pitching elbow pointing at home plate.

&nbsp&nbsp&nbsp&nbsp Therefore, driveline height is slighly above the top of the head.

&nbsp&nbsp&nbsp&nbsp When my baseball pitchers drive their pitching forearm to 'Release,' their pitching elbow comes to a complete stop.&nbsp This is the force-coupling action of my baseball pitching motion.

&nbsp&nbsp&nbsp&nbsp Force-coupling occurs when athletes apply parallel and oppositely-directed forces on both sides of a fulcrum.

&nbsp&nbsp&nbsp&nbsp With regard to baseball pitching, the fulcrum is the elbow joint and the Latissimus Dorsi muscle stops the pitching upper arm from moving farther forward and the Triceps Brachii muscle extends the pitching elbow and the Pronator Teres muscle pronates the pitching forearm forward.

&nbsp&nbsp&nbsp&nbsp Like a booster rocket, these parallel and oppositely-directed forces increase the acceleration rate of the wrist, hand, fingers and baseball toward home plate.

&nbsp&nbsp&nbsp&nbsp c.&nbsp 'Release.'

&nbsp&nbsp&nbsp&nbsp 'Release' shows the position of the pitching arm, the glove arm, the hips, the shoulders, the glove upper leg, their glove foot and the pitching upper leg.

&nbsp&nbsp&nbsp&nbsp At about 0.003 seconds after release (fifteen frames of film running at five hundred frames per second), the position of 'Maximum Pronation' occurs.&nbsp The degree to which the palm of the pitching hand outwardly rotates determines the intensity of the pronation action.

&nbsp&nbsp&nbsp&nbsp If the palm of the pitching hand outwardly rotates to face upward, then my baseball pitchers inwardly rotated their pitching upper arm and pronated their pitching forearm as powerfully as possible.

05.&nbsp In the sixth video segment, I show high-speed film of my pitchers from the side view.

&nbsp&nbsp&nbsp&nbsp High-speed film from the front view shows from where my baseball pitchers start the acceleration phase of their pitching motion, how they accelerate their pitches through release and how they decelerate their pitching arm and body.

&nbsp&nbsp&nbsp&nbsp To focus on the critical moments of the baseball pitching motion, I freeze framed the film at four different moments.

&nbsp&nbsp&nbsp&nbsp a.&nbsp 'End of the Pendulum Swing.'

&nbsp&nbsp&nbsp&nbsp The side view shows how my baseball pitchers move the baseball backward.

&nbsp&nbsp&nbsp&nbsp Visitors should take care note of how far behind the pitching rubber that my baseball pitchers take their pitching hand, when my baseball pitchers walk forward off the pitching rubber and where their pitching hand is when their glove foot lands.

&nbsp&nbsp&nbsp&nbsp When the glove foot lands, baseball pitchers immediately start to accelerate the baseball toward home plate.&nbsp Therefore, when the glove foot lands determines the end of the pendulum swing.

&nbsp&nbsp&nbsp&nbsp Visitors should note how far my baseball pitchers step with their glove foot and whether the heel of their glove foot contacts the ground first.

&nbsp&nbsp&nbsp&nbsp In the 'Maximum Pitching Forearm Acceleration Position,' my baseball pitchers have their pitching elbow slightly above the top of their head with their pitching forearm horizontally behind their pitching elbow pointing at home plate.

&nbsp&nbsp&nbsp&nbsp Therefore, driveline height is slightly above the top of the head.

&nbsp&nbsp&nbsp&nbsp When my baseball pitchers drive their pitching forearm to 'Release,' their pitching elbow comes to a complete stop.&nbsp This is the force-coupling action of my baseball pitching motion.

&nbsp&nbsp&nbsp&nbsp Force-coupling occurs when athletes apply parallel and oppositely-directed forces on both sides of a fulcrum.

&nbsp&nbsp&nbsp&nbsp With regard to baseball pitching, the fulcrum is the elbow joint and the Latissimus Dorsi muscle stops the pitching upper arm from moving farther forward and the Triceps Brachii muscle extends the pitching elbow and the Pronator Teres muscle pronates the pitching forearm forward.

&nbsp&nbsp&nbsp&nbsp Like a booster rocket, these parallel and oppositely-directed forces increase the acceleration rate of the wrist, hand, fingers and baseball toward home plate.

&nbsp&nbsp&nbsp&nbsp c.&nbsp 'Release.'

&nbsp&nbsp&nbsp&nbsp 'Release' shows the position of the pitching arm, the glove arm, the hips, the shoulders, the glove upper leg, their glove foot and the pitching upper leg.

&nbsp&nbsp&nbsp&nbsp At about 0.003 seconds after release (fifteen frames of film running at five hundred frames per second), the position of 'Maximum Pronation' occurs.&nbsp The degree to which the palm of the pitching hand outwardly rotates determines the intensity of the pronation action.

&nbsp&nbsp&nbsp&nbsp If the palm of the pitching hand outwardly rotates to face upward, then my baseball pitchers inwardly rotated their pitching upper arm and pronated their pitching forearm as powerfully as possible.

&nbsp&nbsp&nbsp&nbsp When we methodically evaluate how my baseball pitchers perform my baseball pitching motion with each of the six baseball pitches in the manner that I describe above, then we can better understand what they need to do to become the best, injury-free, highly-skilled baseball pitcher that they can be.

&nbsp&nbsp&nbsp&nbsp Because I take five hundred frames per second high-speed film and make these DVDs of my baseball pitchers, I know exactly how my baseball pitchers apply force to their pitches.&nbsp And, I want everybody else to know as well.

&nbsp&nbsp&nbsp&nbsp That is what Professor Heusner and I call, 'Coaching.'

&nbsp&nbsp&nbsp&nbsp The failure of 'traditional' baseball pitching coaches to analyze high-speed film of their baseball pitchers is the reason why they continue to teach their baseball pitchers the injurious flaws that destroys their pitching arms and bodies.&nbsp Without high-speed film, pitching coaches have no idea of how their baseball pitchers apply force to their pitches.
